Introduction: Pneumatosis cystoides intestinalis is a rare condition characterized by the presence of gas cysts in the intestinal wall. It can affect different segments of the digestive tract. Male patients over 50 years old seem to be more affected. Classically, one opposes the primary or idiopathic forms and the secondary forms. Case Report: We report the case of a 62-year-old female patient with a history of treated peptic ulcers, who presented with episodes of intermittent atypical abdominal pain that worsened abruptly. The physical examination revealed a surgical abdomen with tenderness to palpation. The patient underwent a jejunal resection. The pathological examination showed macroscopically an intestinal fragment with confluent subserosal and intestinal intraparietal bullae. On opening, the portion containing the bullae was thickened, infarcted, congestive, hemorrhagic, and brittle with narrowing of the intestinal lumen. The bullae are tense and leave serosities. On histological examination, the intestinal wall was very congestive with hemorrhagic patches of suffusion. There were optically empty cystic formations that do not communicate with the digestive lumen. The adjacent mucosa is the site of a moderate subacute inflammatory reaction. Conclusion: Pneumatosis cystoides intestinalis is a rare and usually benign pathology. The symptoms, when they exist, are not specific. Its physiopathology is still very much debated. The prognosis is generally good. The knowledge of this pathology is necessary to avoid invasive explorations and heavy treatment without interest for the patient.

Cerebral aspergillosis commonly affects immunocompromised hosts, primarily patients on immunosuppressive therapy and those with acquired or immunodeficient states such as AIDS. We report a case of cerebral aspergillosis in a 39-year-old woman with a history of treated chronic lymphocytic leukemia (CLL). Multiple fragments of fixed tissues with formalin were freshly sent to the laboratory. An extemporaneous examination was performed by spreading. The rest of the sample was embedded in paraffin and studied according to the standard histological method with special stains and an immunohistochemical study. A microscopic observation showed abundant clusters of tangled mycelial filaments, Grocott+. At the edge, a nervous tissue was observed remodeled by an abundant inflammatory infiltrate consisting essentially of small lymphocytes and plasma cells. Additional immunohistochemistry was performed using anti-CD20, anti-CD3, anti-CD5, anti-CD23, anti-Bcl2, anti-Ki67, anti-IgD and anti-Kappa and Lamda antibodies. All taken together there were no further founding in support of a secondary localization of CLL. Cerebral aspergillosis is quite rare and often occurs in a context of immunosuppression. This case indicates the importance of a close collaboration between clinicians and pathologists for optimal patient care.

Introduction: The coexistence of tuberculosis with axillary lymph node metastasis in breast carcinoma is uncommon. Observation: We report a case of a patient aged 59 years presenting a painless nodule in the right breast for one year. The scan and mammography revealed a long-axis node of 3 × 2 × 1 cm in the upper outer quadrant of the right breast ranked stage IV by the American College of Radiology (ACR), associated with a set of axillary lymph nodes and the largest one measuring 15 × 15 × 20 millimeters (mm). The breast biopsy helped diagnose a Scarff Bloom Richardson (SBR) grade II non-specific invasive carcinoma, modified by Ellis and Elston. A right mastectomy associated with a lymph node dissection was performed. We noticed a not well defined and whitish 5 mm tumor mass associated with 16 lymph nodes removed. The histological examination confirmed the diagnosis of SBR grade II non-specific invasive carcinoma with invasion of 7 lymph nodes (N+ = 7/16). In 3 metastatic lymph nodes, there were epithelioid and gigantocellular granulomas with full central necrosis. The Ziehl Neelsen staining had highlighted acid-fast bacilli. The tumor was oestrogen and progesteron receptor, without an overexpression of the oncoprotein human epidermal growth factor receptor 2 (HER2), which corresponds to a 0 score and the Ki 67 proliferation index assessed at 10%. The patient was given an anti-tuberculosis treatment combining Rifampicin (H), Isoniazid (I), Pyrazinamid (Z), Ethambutol (E) over 2 months and secondly a combination of Rifampicin and Isoniazid over 4 months (2RHZE/4 RH). The anti-tumor chemotherapy used a protocol combining 3 FAC60+ 3 Docetaxel (F = Fluorouracil®A = Adriblastin®, C = Cyclophosphamid). Conclusion: This coexistence is uncommon, of incidental discovery and necessitates a multidisciplinary care.

Introduction: Cervical cancer, caused by persistent high-risk human papillomavirus (HPV) infection, remains a global public health problem. The cellular transformation and maintenance of the malignant phenotype of these HPVs are attributed to the viral oncoproteins E6 and E7. Objective: This study aims to detect the presence of human papillomavirus DNA and E6/E7 oncoprotein mRNA of HPV genotypes 16, 18, 31 and 33 in cases of cervical cancer and precancerous lesions, histologically confirmed in Burkina Faso. Methods: This descriptive cross-sectional study focused on cases of cervical cancer and high-grade intraepithelial neoplasia (CIN) and was conducted from June to December 2022. One hundred (100) samples of fixed and paraffin-embedded tissues were collected from the pathological anatomy and cytology laboratories of hospitals in the capital of Burkina Faso. High-risk human papillomavirus (HR-HPV) DNA was detected using multiplex real-time PCR, while the presence of E6 and E7 mRNA in cervical cancer and high-grade CIN samples was determined using real-time Reverse Transcriptase-PCR (RT-PCR) with TaqMan probes. Results: The mean age of women diagnosed with cervical cancer and high-grade CIN was 50.81 ± 13.65 years, ranging from 22 to 82 years. Cervical cancer and high-grade CIN were positive for at least one high-risk human papillomavirus (HR-HPV) in 80% of cases. The most prevalent genotypes observed were HPV16, 18, 31, and 33, collectively accounting for 70.08% of cases. Of the 89 samples that tested positive for HR-HPV genotypes 16, 18, 31, and 33, 88 (98.88%;95% CI: [94.58 - 99.94]) were also positive for the presence of mRNA encoding the E6 and E7 oncoproteins of HPV16, 18, 31, and 33. Conclusion: In the presence of HPV DNA, testing for E6 and E7 oncoprotein mRNA could serve as a promising biomarker and valuable tool for improved assessment of the progression to cervical cancer.

Sanitation is a particularly sensitive issue in the world, especially in Africa where local communities are plagued by the problem of managing sludge which is causing a lot of damage in Africa and mainly in Cameroon. This study aims to contribute to improving the management of sewage sludge in the municipality of Bafoussam 1st. For this study, the methodology used is field survey. The questionnaire was submitted to 120 households in the commune of Bafoussam 1st, in particular, we take into account knowledge of the health and environmental risks that can result from improper handling of sludge and its treatment. The results show that the most widespread sanitation system is traditional latrines. Similarly, 79.19% of those surveyed dump, the sludge collected at the landfill against only 14.28% who dump it in fields and 6.53% have no idea about the fate of the sludge from their sanitary facilities. It should also be noted that 55.83% of the people surveyed are not aware of the health and environmental risks of untreated sewage sludge and therefore do not take the precautions to avoid it. Subsequently, 93.75% of respondents say that the current landfill would be a nuisance and the main nuisances identified are water pollution and subsequent fish poisoning. Physico-chemical analyzes of the sludge revealed values much higher than the values provided for by the WHO standards. Thus, total nitrogen and phosphate ions represented respectively 97 mg/L and 47 mg/L against 35 and 30.4 mg/L for the standard;COD and BOD5 represented respectively 3250 mg/L and 1100 mg/L against 150 and 40 mg/L provided by the WHO standards. It follows the temperature and the MES which gave values of 32.7°C and 1750 mg/L, values much higher than the standard (30°C and 50 mg/L).

Edible Wild Fruit Highly Consumed during Food Shortage Period in Togo： State of Knowledge and Conservation Status

引用

Journal of Life Sciences 2011年第12期5卷 1046-1057页

作者： Abalo Atato Kperkouma Wala Komlan Batawila Nieyidouba lamien Koffi Akpagana Laboratoire de Botanique et Ecologie Vegetale Faculte des Sciences Universite de Lome Lome B.P. 1515 Togo Centre Regional de Recherches Environnementales et Agricoles （CRREA） du Centre Koudougou B.P. 10 Burkina Faso

The aim of this work is to inventory Edible Wild Fruit Species （EWFS） highly consumed by local people during food shortage periods in Togo. Ethnobotanical surveys were carried out in four ecological zones （I, II, III ＆ IV） involving a sample of 433 persons from 29 ethnic groups. Semi-structured interview, field observation, group discussions were used to collect data. Food shortage periods were defined using the agricultural calendar of main crops in three ecological zones （I, II, ＆ III）. One hundred and one EWFS belonging to 84 genera and 39 families were inventoried. The three main types of use of the EWFS were direct consumption, condiments and medicines. Twenty among the 101 EWFS recorded were highly consumed during food shortage periods with respectively 15 EWFS in ecological I, 14 in zone 1I and 12 in ecological zone III. All edible fruits consumed during food shortage periods were fresh fruits with abundant pulp. Six fruit species were sold to bring income to local households. These species were those which benefit from conservation measures through their husbandry in agroforestry systems.

Stabilization of a Lateric Clay from Burkina Faso with Cement-Metakaolin for an Application in Road Construction

引用

Journal of Materials Science and Chemical Engineering 2023年第6期11卷 1-20页

作者： Souleymane sanou Issiaka sanou Moussa Ouedraogo Halidou Bamogo Lohami Valentin Landry Gnoumou Younoussa Millogo Seynou Mohamed Laboratoire de Chimie et Energies Renouvelables (LaCER) Département de Chimie Université Nazi BONI (UNB) Bobo Dioulasso Burkina Faso Laboratoire de Chimie Moléculaire et des Matériaux (LC2M) Département de Chimie Université Joseph KI-ZERBO (UJKZ) Ouagadougou Burkina Faso

The objective of this work is to obtain a composite of clay-cement-metakaolin having good mechanical properties and geotechnical. To do this, a lateritic clay from Burkina Faso referenced ALK was characterized by various methods (X-ray diffraction, infrared spectrometry, thermal analysis and Inductively Coupled Plasma, Atomic Emission Spectrometry) in order to be used as a base course after adding cement and metakaolin. The results of the mineralogical characterization of this clay showed that it is composed of kaolinite (65.7 wt.%), quartz (19.3 wt.%) and goethite (10.8 wt.%). The geotechnical tests carried out showed that ALK is moderately plastic with a plasticity index Ip = 22%. The optimum moisture content and the maximum dry density are respectively 15.9% and 1.76 g∙cm-3. Simple compressive strength and splitting tensile strength are Rc = 1.59 MPa and ft = 0.149 MPa respectively. The California Bearing Ratio (CBR) index at 95% is 40% and above the minimum value of 30% shows that ALK can be used as a sub-base course in road construction. The addition of cement and metakaolin in various proportions improved the CBR index and the mechanical strength of the composites produced. This improvement is due to the formation of hydrated calcium silicate (CSH) resulting from the pozzolanic reaction between the portlandite of the cement and the amorphous silica of the metakaolin. Thus the 2 wt.% metakaolin and 6 wt.% cement formulation with a 95%CBR index of 81% is suitable for the development of a base course in road construction.
